Betty Lou Jensen Autopsy:There are five bullet wounds of entry on the right side of the back: three on the posterior chest cage and two over the right lower posterior lumbar areas. From up downwards:[1] The first is located in the 5th intercostal space, 3 and 3/4 inches right of the midline.[2] The second is in the 8th intercostal space, 5 and 1/2 inches from the midline.[3] The third is in the 9th intercostal space, 1 and 1/2 inches from the midline.[4] The fourth in the tip of the right 12th rib, 3 and 1/2 inches from the midline.[5] The fifth is over the crest of the posterior right iliac bone and 5 and 1/2 inches from the midline.​There are three exit wounds:​[1] The first is over the left interior chest laterally and left margin of the breast, in the 4th intercostal space and 5 and 1/2 inches from the sternum.[2] The second is in the anterior abdominal wall, below the xyphoid process and 1/2 an inch from the midline.[3] The third is laterally and 3 and 3/4 inches to the right of the umbilicus.

Heart: A bullet wound penetrates from right to left through both atrium.Lungs: There are three through and through bullet wounds, corresponding to the three bullet wounds of entry on the right posterior chest cage and one bullet wound through the left lung, in line with the wound through the heart. They are associated with extensive hemorrhage of both lungs.Abdominal Cavity: A bullet wound penetrates the liver. A bullet wound penetrates the right kidney, the left is normal.Head: No injuries or skull fractures.The bullet wound over the posterior iliac crest penetrates the deep musclesand exits to the right of the umbilicus. One bullet is recovered in the subcutaneous tissue of the base of the anterior neck (left side) and the other bullet in the subcutaneous tissue anterior to the right 7th rib, which it penetrated of the sternum. The entry wounds aperture 3/16 inch in diameter. The exit wounds are larger.

On the right the three exit wounds are marked with the letter E on Betty Lou Jensen's back. These exit wounds obviously exited the front of her body relative to the positions shown, but have been placed on the back to highlight the difference between the entry wounds and exit wounds. The other two red dots show the resting position of the remaining bullets within the body.​One can see that four of the bullets that exited or remained in the body, are all situated to the left of the entry wounds, the fifth bullet traveled from right to left also. Bullets do not necessarily follow a linear trajectory when they enter the body, they can be deflected by the body's structures, but here the pattern of all five bullets show a distinct right to left trajectory. This means the idea that Betty Lou was ordered to run from her killer, with the shooter standing directly behind her, is simply false. We would have to believe the notion that every single bullet that struck Betty Lou Jensen was deflected to the left. What it also means is that if the uppermost wound was the first shot, on account of the gunpowder residue, this shot was likely fired at an acute angle. In the autopsy it states 'A bullet wound penetrates from right to left through both atrium; and one bullet wound through the left lung, in line with the wound through the heart', in direct alliance with the photograph on the right.​

On the left is a police sketch of the scene. The cluster of red dots indicate the region the shooter was standing when he discharged at least 8 of his rounds. The green arrow signifies the direction of Betty Lou Jensen's path of movement away from the shooter, from east to west. Had the Zodiac fired 5 shots into Betty Lou Jensen while positioned between the two vehicles, then he was standing directly behind her. This would mean that every single bullet that struck the right side of her back just happened to deflect left, as shown by the autopsy diagram.The trajectory of the bullets seem to indicate she was struck while running across the shooter's line of sight, or possibly stationary at some point. Betty Lou was found with her head facing eastwards, toward the Rambler, likely as a result of her legs buckling under her, and falling backwards. Her head was approximately 28 feet from the rear of the Rambler, her lower extremities slightly further than 33 feet away.​
